Improvement in lubricators



PATENT EEICE. y

`WILLIAM ACLAEK, CE wEsTvILLE, CONNECTICUT.`

To all whom t 'mag/concern:

`Be it known that I, WILLIAM A. CLARK, of Westville, in the county ofNewHaven and State of "Connecticut, have invented certain Improvementsin- Lubricators, 0I' which the following is a specification, referencebeing` had to the' accompanying drawing.

My invention relates to lubricators for use. on steam-engines and pumps;and consists in constructing the same with an upper steamchamber and alower oil-chamber, so that the oil shall be displaced and fed out bywater resulting from the Condensation of steam in the upper chamber, ashereinafter described.

y Figure 1 is a vertical section through the center of my lubricator,and Figs. 2 and 3 are t, views of detached parts ofthe same.

In constructing ni y lubricator I Iirst provide g an oil-reservoir orchamber, A, consisting of H a glass cylinder, having two metal heads orend pieces, b, applied to it, and held in place by screwrods or bolts c,as shown in Fig. 1. I next provide a tight metal steamchamber, `C, andconnect its lower `endwith the top of the oil-chamber A, by means of atube l), as shown. Theconnecting-tube D I provide with a'cock, E, bywhich the communication between the steam aud oil-chamber may be closed;and to the cock I connect a depending-tube, F, 'extending down to nearthe bottom of the oilchamberA, as shown, thetube bein g so connect`edthat everything passing through the opening d of the cock tlows downthrough the tube into the bottom of the oil-chamber A, as shown inFig. 1. On the side of the connecting-tube D, at the back end of cock E,I form a small chamber, J, and connect the same by a tube, G, with thesteam-chamber C. I also make in the back end of the cock E an L-shapedhole or passage,- c, one end ot' which opens through the side of thecock, and the other through the end ofthe saine into chamber J, so thatwhen the'vcock is set in the position shown in Fig. l `the lhole 'e`forms a communication between the oil-cliamber'A and chamber J, whichcommunication may be closed or graduated by turning the cock E. Thepassages d and e in the cock are so arranged that by turningthe cock)far enough communication may be closed between the steam andoil-chambers, and beftween the oil-chamber A and chamber J atIMPROVEMENT IN L uBRicAToRs.

`the same time; but the passage-d is made larger than e, so that it doesg not close until after `the other, whereby the flow of oil may be regu-1 lated without shutting ofi" completely the down-` liow ofthe water.Tothe chamber J, I connect a pipe, H, which serves both to convey steamto the chamber or condenser C, and oil from the chamber A to the partsto be lubricated. In applying the lubricator to the steam or valve-chestof an engine I placek it above the same and connect the pipe Htherewith, and g then iill the chamber or reservoir A with oil, andopenl the cock D, as shown. The steam tlows through the pipe H intochamber Tand thence through pipe G int-o the chamber C, which remainsconstantly filled therewith. As the outside of the chamber O is incontact with the atmosphere, a portion of the steam therein isconstantly undergoing condensation or conversion into water, and thiswater, as fast as produced, flows down through the` passage d in thecock, and through tube F into the bottom of the oil-chamber A. The waterbeing heavier than the oil displaces the same, and causes it to rise-andtlow through the passage e in the cock into the chamberJ,fro1n whence itiiows down in the bottom or lower part of pipe H to the en gine.l Thisoperation continues until the' oil-chamber A is filled with water, andall the oil forced out, when the water is drawn o'iI' and theChamber,relled with oil. The oil-chamber is provided with a cock, M, atits lower end for drawing` oii the water, and a funnel and cock, 0, atits top to allow the ready introduction of oil. The steamchamber` C isalso provided with a cock which is opened to permit the escape of theair therein when commencing operation.

It will be observed that when the lubricator is in operation the steampasses to it and the oil from it through one and the same pipe, H, whichis the only communication or connection between the lubricator and theengine. The steam passes along through theupper portion of the pipe, andthe oil through the lower portion of the same, both passing through thepipe at the same time but in opposite directions. By turning the cock Ethe size of the opening e may be 'regulated so as to vary the iiow ofoil,` as may be necessary. To aid in regulating or adjusting the cock,and to indicate theamountlof xcil bing'fed out, I providetli' cock withlark's or grad'uatiohs, and its seat( with a single mark or line, asshown in Fig. 3, so that the positions of the cock are indica-ted by thepresence of one or another of the graduations opposite theline. A i YInstead of usi'lg the cock Efcha'lei" J, -iid pipe G, asv shown, theymay be dispensed with, and then instead of using lthe pipe Hasteampipe,R, may be conn ected directly t`o the ber O, and an oil-pipe, S, carriedfrom the 11p- Y per end of the oil-chamber A directly tothe engine, asshown by dotted lines in Fig. 1. In such case the operation Will besubstantially the saine as before, the steam condensing in Chamber c,flowing kk(lawn through 11.1599 the climber A, and theft spitting the@i1 and. easing' megane inflow 'off.t-fufoiugh.pip'ejS.
